Why is the unit price of ten licenses purchased together higher than the price of a single purchase?

you need to decrease the tolerance value to 0.001 on your browser to get the accurate read

Looks like this is just a typo. The reseller store site has the correct price of 9950. Note this item is a *single-key 10 user license*, not 10 single licenses - the price is the same of course, but the item is different.

Thanks @Archi-BC this is noted and will be fixed shortly.
